Abstract- Multipurpose cadastre has capability to store, manipulate, analyse and retrieve parcel based land related information. In this study, a multipurpose cadastre was developed and implemented for Udoka Housing Estate, Awka in Anambra State of Nigeria. The spatial and geometric data were acquired by land surveying techniques using a second order Wild T2 theodolite and standardised steel tape, while the attribute data were obtained by groundtruthing. The layout plan was produced with AUTOCAD 2007 software using the adjusted coordinates of the beacons. This hardcopy layout plan was converted to digital layout plan through scanning, georeferencing and digitising. Arc GIS 9.2 software was used to perform GIS operations of storing, processing, manipulating, analysing and displaying of desired information. Multipurpose cadastral information layers were created for roads, parcels, beacons, residential buildings and perimeter lines. Queries were created to demonstrate the effectiveness of the developed multipurpose cadastre. These queries among others are query for roads that are not bad, query for developed and undeveloped parcels, query for parcels with duplexes ad bungalows, query for parcels that are used for residential and non-residential purposes, query for parcels whose owners are from Anambra State and query for parcels whose owners are females. The result shows that 83.78% of the total plots were developed while 16.22% were undeveloped. Out of the 83.78% developed plots, 62.37% were duplexes while 37.63% were bungalow. Also, only 2 plots or 1.8% were reserved for non-residential purposes. The results of the various queries and analyses shows that a multipurpose cadastre is a veritable tool for decision making in land related matters and should be adopted for successful implementation of the Land Reform Programme of the Federal Government of Nigeria.

1. INTRODUCTION
Land is a basic resource for wealth creation, and on it activities of man take place. Efficient information on land is a good foundation for wealth creation and national development. Because of the vital role it plays in human affairs vis-à-vis the source of most wealth, land should be properly managed. To effectively manage land and its resources, comprehensive information about land should be
recorded in an organised and robust manner to enable quick and flexible access to land related information. Land information is a prime requisite for making decisions related to land investments, development and management [1]. Multipurpose cadastre enables good land management by providing reliable and usable land information [2]. Multipurpose Cadastre is therefore a veritable tool for effective decision making in land related matters [3][4]. A functional land based Multipurpose Cadastre

provides timely, accurate and up-to-date information about parcels of land which can prevent mismanagement and wrong decision in land matters [5].
As a result of population increase, urbanisation and industrialisation in Awka Capital Territory (10 kilometre radius from Amawbia Junction through Old Onitsha/Enugu Road), there is enormous pressure on, and demand for land resources in Awka and environs. The Ministry of Lands, Survey and Town Planning, Awka charged with the responsibilities of land allocation and management in Anambra State has not fully computerised land related data, plans and records. Administration and management of land and its resources by the ministry are by the use of analogue files, records and plans. Data storage, processing, manipulation, analyses, update and retrieval are very difficult tasks for the ministry. This situation has resulted into data losses and wearing out of analogue files, records and plans. The ministry is presently faced with unattended applications, multiple and fake allocations, forgeries of land documents, encroachments, court cases, and poor internally generated revenue (IGR). Furthermore, some of the spatial data held by the Ministry do not have common reference coordinate system. Many are still referenced to local origins such
as CS 316 for Awka, U21 for Onitsha, NCSIP for Nnewi, EKCSIT for Ekwulobia, UMCSIT for Umunze, etc. These problems hamper good decision making in land related matters in the State. The development and implementation of a Multipurpose Cadastre (MPC) using Udoka Housing Estate, Awka, Anambra State, as a prototype case study could be used to demonstrate how its adoption would facilitate land administration and management in Anambra State, Nigeria.
II. MATERIAL AND METHODS USED
A. Study Area Udoka Housing Estate, Awka is located along Onitsha/Enugu Express Road (opposite NNPC Mega Station) Awka, Awka South Local Government Area, Anambra State, Nigeria. The site lies approximately within latitudes 60 12’ 19” N and 60 12’ 39” N, and longitudes 70 03’ 26” E and 70 03’ 51” E. It is a medium density estate or layout planned, developed and managed by Anambra State Housing Development Corporation, Awka. The case study site has an area of about 15.188 Hectares and 111 parcels. Its location along Onitsha/Enugu Express Road on Ikwodiaku Hills in Awka makes the site conspicuous and fascinating.

B. Data Used
The data used for development of the Multipurpose Cadastre (MPC) were classified into two Primary data and Secondary data. Primary data are both spatial and attribute (non-spatial) data which were obtained through ground survey methods, enquiries and observations.
The spatial data were survey data (X, Y co-ordinates) which described the spatial locations/positions of the parcels and other entities in the real world obtained through traditional surveying technique. The non-spatial (attribute) data include ownership details, allottee details, land use, building types, as well as descriptive information about entities of interest in the study area.
The secondary data include the following:
i. Administrative map of Anambra State containing Awka South Local
Government Area where the project site is located.
ii. Udoka Housing Estate Awka, Layout Plan
iii. Horizontal Coordinates (X, Y) of survey controls to be used for linking the layout survey to the national geodetic control network.
C. Data Processing and Analysis
The layout plan of the study area was scanned and imported into ArcGIS software where it was georeferenced and digitized. The spatial and attribute data were used to create the database. Attribute tables were created for the beacon numbers, roads, perimeter line, parcels etc. Information contained in the attribute tables include length, name, conditions of roads, parcel ids, owners, state of origin, parcels, beacon numbers and coordinates, etc. Figure 2 shows the Entity-Relationship diagram of the database created.

III. RESULTS AND DISCUSSION
Results of the database queries were presented in digital maps and attribute tables. The result of sample queries performed on the databases and their results are discussed below.
Query 1: How many parcel of land are developed and undeveloped?
Fig 3.1: Query result showing the plots that were developed and undeveloped.
The green-colored plots were the developed plots
while the undeveloped were left plain. The query
result gives pictorial view of the number of developed
and undeveloped parcels in the layout. The result can
also aid decision making on provision of facilities, re-
allocation of undeveloped parcels and enhanced
revenue collection through property tax. As more
parcels are developed, more occupants are attracted,
and thereby increasing the population of residents of
the estate. The query result can equally aid decision
making on how to cater for the facility needs of the
residents of the estate. Also table 1 shows the attribute
table of the result of the query.

The Udoka Housing Estate scheme permits only
erection of duplexes and bungalows. The green-
colored plots in Fig. 3.2 were the plots with duplex
while the plain ones are those with bungalow. The
query result could aid in development control in the
layout. The result of the query could also aid in
getting accurate revenue statistics in the layout as
there is obvious disparity in the property taxes paid
by duplex owners and bungalow owners. Table 2
shows the attribute table of the result of the query.

Query 3: What are the parcels that are used for residential and non residential purposes.
Fig.3.3: Query result showing residential and non-residential plots.
The query result reveals that only two parcels (B1 and
B2) are used for non-residential purposes. The
management of the estate could be aided in making
decisions on the sufficiency or otherwise of the two
parcels used for social/recreational purposes. The
attribute table of the plots is presented in table 3.

4.0 Conclusion and Recommendations
4.1 Conclusion
The project was able to achieve its primary goal
which was the design and implementation of a
prototype multipurpose cadastre for Udoka Housing
Estate, Awka to demonstrate its usefulness in efficient
administration and management of land
resources.The procedures adopted in the
development of the prototype multipurpose cadastre
included map data collection, scanning,
georeferencing, digitisation, spatial and attribute data
creation and queries. The Arc GIS 9.2 software was
used in the study. The thematic layers created in the

study included roads, parcels, beacon numbers, residential buildings (RB) and perimeter lines.
It is strongly believed that the adoption and
implementation of a statewide multipurpose cadastre
based on the results of this prototype case study will
greatly enhance the activities of various ministries
and agencies in Anambra State that deal with land
resources and other environmental matters.
4.2 Recommendations
1. For successful implementation of the Land
Reform Programme of the Federal
Government, implementation of a
nationwide multipurpose cadastre is
strongly recommended.
2. There is a great need for the conversion of
local coordinate systems used in all states of
the Federation to the National Grid.
3. There is urgent need for training and
updating of surveyors in the operations, use
and management of digital systems, spatial
analyses, remote sensing and image
processing techniques.
4. Public enlightment programmes should be
organised to educate members of the public
and governmental agencies on the potentials
of multipurpose cadastre as a veritable tool
for making decisions on matters related to
land.
5. The Survey Laws should be amended to give
legal backing to the use of digital
equipments for data acquisition, processing,
analyses and presentation.
